Category:Cone Beam X-ray

In modern dentistry, the need for more advanced imaging techniques is constantly growing. Traditional two-dimensional computed tomography (CT) generates the image of multiple axial slices, whereas three-dimensional radiography captures the entire volume needed in a single half-circle scan. Consequently, the patient is exposed to radiation for a significantly shorter time.

The imaging technique is based on new CBVT technology (Cone Beam Volumetric Tomography, also called CBCT - Cone Beam Computed Tomography), in which the X-ray beam has a shape of a cone or a pyramid. The operating principle of CBVT is a lot simpler than that of the traditional CT. However, CBVT technology requires an easily read full-field radiation sensor and high computing capacity for image processing.

3D tomography is an excellent diagnostic tool for implantology, dental and maxillofacial surgery, endodontics, orthodontics, and TMJ analysis. It can also be successfully used in diagnosing ear, maxillary sinus, and respiratory tract diseases.

Cone beam units are small in size and rather inexpensive compared to medical CT units, which brings them within reach of dentists and dental radiologists. Previously three-dimensional images could only be taken in a hospital with the larger medical CT scanner.
